      amdgpu/pm: Fix possible array out-of-bounds if SCLK levels != 2 · ceb18036
      Darren Powell authored 
       [v2]
simplified fix after Lijo's feedback
 removed clocks.num_levels from calculation of loop count
   removed unsafe accesses to shim table freq_values
 retained corner case output only min,now if
   clocks.num_levels == 1 && now > min

 [v1]
added a check to populate and use SCLK shim table freq_values only
   if using dpm_level == AMD_DPM_FORCED_LEVEL_MANUAL or
                         AMD_DPM_FORCED_LEVEL_PERF_DETERMINISM
removed clocks.num_levels from calculation of shim table size
removed unsafe accesses to shim table freq_values
   output gfx_table values if using other dpm levels
added check for freq_match when using freq_values for when now == min_clk

      amdgpu/pm: Fix incorrect variable for size of clocks array · 543faf57
      Darren Powell authored 
       [v2]
No Changes, added RB
 [v1]
Size of pp_clock_levels_with_latency is PP_MAX_CLOCK_LEVELS, not MAX_NUM_CLOCKS.
Both are currently defined as 16, modifying in case one value is modified in future
Changed code in both arcturus and aldabaran.

Also removed unneeded var count, and used min_t function

      drm/amdkfd: Free queue after unmap queue success · ab8529b0
      Philip Yang authored 
      After queue unmap or remove from MES successfully, free queue sysfs
entries, doorbell and remove from queue list. Otherwise, application may
destroy queue again, cause below kernel warning or crash backtrace.

For outstanding queues, either application forget to destroy or failed
to destroy, kfd_process_notifier_release will remove queue sysfs
entries, kfd_process_wq_release will free queue doorbell.

      drm/amd/display: fix incorrect comparison in DML · eec53143

      [Why&How]
GCC 12 catches the following incorrect comparison in the if arm

Fix this by remove preceding & so that value is compared instead of
address

      drm/amd/display: fix array index in DML · c85c623a
      Aurabindo Pillai authored 
      [Why&How]
When the a 3d array is used by indexing with only one dimension in an if
condition, the addresses get compared instead of the intended value stored in the
array. GCC 12.1 caught this error:

drivers/gpu/drm/amd/amdgpu/../dal-dev/dc/dml/dcn32/display_mode_vba_32.c: In function ‘DISPCLKDPPCLKDCFCLKDeepSleepPrefetchParametersWatermarksAndPerformanceCalculation’:

605 | bool use_one_row_for_frame_flip[DC__VOLTAGE_STATES][2][DC__NUM_DPP__MAX];
|

Fix this by explicitly specifying the last two indices.
